Abstract:
We present a theoretical study on the inner-shell ionization of Au, Pb, and Bi. A collective response model, the shellwise local plasma approximation (SLPA), is employed, which works within the dielectric formalism. The wave functions and binding energies were obtained in fully-relativistic way by solving numerically the Dirac equation. The theoretical results describe nicely the experimental data for M-shell ionization of Au and Bi above 2MeV/amu, and for L-shell ionization of Au and Pb above 10 MeV/amu. The SLPA tends to underestimate the data for energies below the range of validity of the model and approach to them for higher energies.
